Weiku’s journey began in Germany with the entrepreneurial spirit of technician and businessman Arnd Kilian, who founded his first company, Goedicke & Kilian, specialized in PVC frame assembly, in 1986. In 1990, Weiku Fenster und Türen GmbH was established in the city of Weißenfels. The name Weiku combines Weißenfels and Kunststofffenster (PVC frames in German), reflecting from the start a commitment to innovation, quality, and German precision.

After 15 years operating in the demanding European market, Kilian decided to expand horizons and venture into a new country. In 1998, he chose Pomerode (SC), a city with a strong German heritage, to establish Weiku do Brasil, with the purpose of offering high-performance PVC frames aimed at the luxury market.

Excellence soon was reflected in the company’s rapid growth, which underwent two expansions until it was consolidated in its current manufacturing facility in the Testo Central neighborhood, with over 26,500 m² of built area and space reserved for further expansions.

Since the beginning of its operation in Brazil, Weiku adopted a verticalized structure, with complete control over production. In 2001, the partnership with the multinational Kessel GmbH marked a new phase of investments in technology, enabling the creation of its own line of profiles and a complete extrusion facility.

Today, the Weiku Group has over 700 direct and indirect employees and offers top-tier PVC and minimalist aluminum solutions for residential, commercial, and corporate projects throughout the country. With a branch in Campinas (SP) since 2013, new units are already emerging, following the group’s expansion into other regions of Brazil and Latin America.

More than just a company, Weiku is a family brand built with purpose. The work started by Arnd Kilian continues with the new generation, which actively leads the business:

• Philipp Kilian, Commercial Director
• Julius Kilian, Production Coordinator
• Leon Kilian, Financial and Administrative Coordinator
• Oliver Frederik Kilian, Architecture student and member of the Projects team

Together, father and sons shape the future of the brand with the same vision of excellence that founded the company, now combined with the strength and energy of a new generation.

Weiku do Brasil is more than a frame manufacturer. It is a brand that transforms projects into experiences of comfort, with precision, sophistication, and soul.
